Now that Google Apps is no longer free, I'm searching for a new email option. I tried playing around with Postfix on a spare computer, and quickly learned that some email providers require reverse DNS to be setup before processing mail from you. I'm trying to learn away from hosting a mail server on my own machine because recently power has not been that reliable. Has anyone found an alternative that works, even if it costs? I thought about setting something up on a VPS, but I'm afraid that my VPS could be terminated at anytime, and all my emails disappear for good.
